LAMP-WORKING APPARATUS.

To all whom it may concern:

Be it known that we, THOMAS C. Loon I and CHARLES ROY SILVERNAIL, both of the is adapted to be attached to vehicles, and

especially automobiles or similar cars, so as to direct the lamp or head light in away to have the rays follow the direction of the wheels as the latter are steered, instead of Our invention is especially intended to produce a very simple attachment which can be applied to any ordinary form ofcar, which can be adjusted so as to give the desired amount of throw or turn to the lamp, which has a little lost motion so that the lamp will not wiggle with the lateral vibrations of the car as it moves over the road, and which is provided with means for easily putting the lamp out of gear so that during the day time the operating mechanism may be out of use, all to the end that an efficient,

simple lamp working apparatus can be used which will not be objectionable in any way but will cause the li ht to turn automatically with the steering of the wheel so as to project the rays at the desired angle.

Reference is,.to behad to the accompany-- ing drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a broken plan view of the apparatus embodying our invention. Fig. 2 is an enlarged detail vertical section of a part of the lamp connections. Fi. 3 is a sec tional plan on the line 3-3 of Fig. 2. Fig. 4 is a broken detail View on an enlarged so. showing the connecting rod and attachments for operating the lamp. Fig. 5 is a sectional elevation showing a modification of our improved apparatus as applied to a car, Fig. (i is a detail section on the line (5- 6 of Fig. 5, and Fig. 7 is a sectional plan on the line 7-7 of Fig. 5.

In the drawings we have shown the usual axle 10 connecting by a knuckle 11 with the wheel, and this knuckle has the customary arm 15?. projecting forward and rovided with a connecting rod 13 which leads across to a similar arm" on the opposite steering Specification of Letters Patent.

knuckle. We have shown the customary knuckle; 11. All this is common to most makes of cars, and forms no part of our invention. We have also shown the customary steering rod 14 connecting as usual with the crank on the under side of the steering lamp bracket 15 which is a forked bracket, and this carries the lamp 16- which can-be of any approved kind. The lamp bracket is supported on a vertical sleeve 17 which is carried by the bracket 18, and this'is fastened to the car frame 19. The bracket 15 1s,how-' ever, provided with a vertical shaft 20 which extends down through the bearing 17' and is locked by means or the screw 21 or equivalent fastening. 'l'urning loosely on the lower .end of the shaft is the hub 22 of the crank arm 23, and the latter has holes 24 therein so that an adj ustabl'e connection can be made with the connecting rod 25 which is coupled to the steering rod 14.- by means of a two- P l lg he parts being clampedto the rod let by means of bolts 21 and the top part of the coupling has..-atongue 28- wnich is pierced by a pin 29 on one end of the steering rod 25. 'lhe spring plate 30 also pierced to receive the pin 2%), is held to' the connecting rod by means of the rivet 31,

and by springing out the spring 30 and turn-,

ing it on its pivot '31, the pin 29 can be removed from the tongue 28 and the connecting rod thus disconnected at this point. A. similar connection is made between the connecting rod 25 and the crank arm 23, in which case the connecting rod has a pin 33 extending through the crank arm and from a. plate spring 50', the latter being like they spring 30 already referred to, and it is pivoted on the pivot 82. It will be seen that it is thus an easy matter to connect or disconnect the rod 25, and by adjusting the pin 33 in either one-of the desired holes 24, the amount of throw to give to the crank arm 23 can be regulated. Just above and in close contact with the crank aim: 23 is a second. crank arm 3* which is fix/ed to the shaft 20 by means of the set screw 35, or equivalent fastening. The arm 3% is provided with teeth 36 between which lit loosely one of the lugs 37 on the pin 37 (see Fig. 3} and the second lug on said pin fits between the teeth 38 which rise from the crankarm 23 already referred to. The pin 37 is helddown normally by means of a spring 39. It will be seen, therefore, that when the rodll. is moved to steer the machine one way or the other, the move.-

' it will of course be understood that with the lamp steadily under ordinary circumbut this would require no invention, simply little lost motion between the lugs 37 and the teeth l 38 and 38, so that as the steering i gear moves slightly owing to obstructions in the road, such movement will not be iinparted to the lamp, and to further provide l against such accidental II10\Gl(-)lll, a plate spring 4-0 is used which is secured to the arm 31- as shown at ll in Fig. 2, and which has bosses l2 formed thereon, which enter recesses ea in the tired sleeve 17. l'hus it will seen that the spring it) will serve to hold stances, but the engagement between the spring i and the slee e is only frictional, and so when the steel g gear is worked to any considerable cjx'ttlil, the movement will 3e imparted to the crank arms 2;, and 3- with siaiiicient force to overcome the tension of the spring ell), and the post 20 and the i lamp bracket will be turned. co-incidentally with and correspondingly to the wheel.

li=it is desired to throw the parts out of j gear during the day time, the pin 37 can be raised. against the tension of the spring 3!) and turned around to right angles to the position shown in Fig. 3, so as to be out of engagement with thetecth 3G and 38, and then it will be seen that the movement of the rod l-l will be only imparted to the arm 23 which wil' turn l'reely on the post 20 without affecting the lamp, or if desired the connecti ing. red can, be wholly disconnected, as l already describtal. when the lamp is not to l he used. We have shown a connection bctween the crank ari J3 and the rod 14;, but

i i l l l diiferent steering gears it might be necessary to connect the arm 23 with some other reciprocating or moving part of the gear,

ordinary adjustn'ient to various gears.

. In Figs. 5 to 7 we have shown some slight modifications which illustrate the tact that the invention is applicable to various forms of steering gear. As here shown the sleeve j or bearing l7 is arranged on a bracket l T. 5 and'the lamp bracket has a spindle I already referred to, and has a boss 1.5 at I the base of the bracket, which boss has an 1 extension 15" fitting in a currcspomliug socket on the top of the sleeve or bearing 17. Aspiral spring El-f'l: is coiled around the spim dle 20 between the hearing or sleeve 17 and l the crank 23, and keeps the boss 15 in close contact with the sleeve 17, and when the parts are in the position shown in Fig. 5, the lamp is held ready for use, but by lifting the lamp bracket against the tension of the spring ll and turning it around, it can be thrown out of use if desired. The crank 23 may be a plain crank or may be like the one already described, and it connects by a pit-- man 253 with the crank -1-5 of the steering gear, this connecting with the steering rod 445, as usual in some types of machine. It will thus be seen that when the steering gear 5 is used, as the crank moves backward and forward to turn the wheels, the lamp bracket will be correspondingly turned and the light will follow the direction of the wheels.

Having thus fully described our invention, we claim as new and desire to secure by Let.- ters Patent 1. In an apparatus of the kind described, the combination with the lamp bracket, of a 1 crank loosely connected therewith, a second crank tightly connected with the bracket,

tcetl'i-arranged in pairs on the two cranks,

and a pin extending through one of the cranks and having lugs to engage both pairs ol teeth.

'4. The combination with a wheeled vehicle having steering gear, of a supporting sleeve, a lamp bracket having a. spindle extending downward through the said sleeve, a spring pressed boss and socket connection between the lamp bracket and the sleeve, a

l crank arm loose on the bracket spindle, a

Srcoiltl crank arm lying near the lirst crank arm, the second arm being tight on the spindle, a detachable connection between the two crank arms, and means for operating one crank from the steering gear of the vehicle.

23. In an apparatus of the kind described, the CtHl'lbllltlllUll with the lamp bracket having a depending spindle and a support for the spindle, ol a crank arm loosely connected with the spindle, a second crank arm tightly connected with the spindle, teeth on the two crank arms, said teeth being arranged in pairs and spaced apart, and apin having lugs thereon, said pin extending through one crank arm and having its lugs adapted to i engage both pairs of teeth or to lie between the'suid pairs ol teeth.
